BURNER FOR VAPOR-STOVES.

SPECIFICATION forming part of Letters Patent No. 372,724, dated November 8, 1887.

Application filed November 11, 1886.

To all whom it may concern:

Be it known that I, \VILLIAM VOGEL, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Burners for Liquid Fuel; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,

IO which form a part of this specification.

This invention relates to a novel burning de vice for liquid fuel of that kind which comprises a receptacle or trough to which theliquid fuel is continuously supplied and in which it is burned such, for instance, as is set forth in a prior application for patent, No. 210,046, filed by me in the United States Patent Office upon the 5th day of August, 1886.

The invention consists in the matters hereinafter described, and pointed out in the appended claims.

The accompanying drawings illustrate an oil-burner embracing my invention as applied to cooking-stoves, several somewhat different forms of the burner being shown.

In the said drawings, Figure 1 is a central vertical section of an oil-burner and parts of the stove adjacent thereto. Fig. 2 is a longitudinal vertical section of the same, taken upon line 00 x of Fig. 1. Fig. 3 is a section similar to Fig. 1, illustrating a burner more especially adapted for use in connection with a cooking stove or range having a waterback. Fig. 4 is another section similar to Fig. 3, showing a modification of the device shown in said figure.

As illustrated in the said drawings, A indieates the top, A the front wall, and A A the side walls, of a stove.

A indicates an inclined inner wall, forming 0 a partition between the iire space or chamber and the oven of the stove, said wall A being connected at its top margin with the horizontal plate A, forming the top of the oven, and also forming the lower wall of the passage A 5 by which the smoke and products of combustion pass from the burner to the smoke-pipe of the stove.

B is an oblong rectangular metal box, consisting of side and end walls, I) b, I) b, and a (No model.)

bottom, B, and provided with two inner ver- 5o tical walls, I) 1), arranged parallel with the outer walls, I) b, and forming an inner recepta ole or trough, B within which is placed the porous or perforated bed 0 of the burner. The spaces between the outer walls of the box B and the inner partition-walls, 1) b form receptacles for receiving oil which may overflow from the trough B. Said bed 0 may be of castiron vertically perforated; or it'may be made of porous material-such as fire-brick or asbestus-or it may consist of a bed of sand, gravel, or other granular substance adapted to give a porous character to the bed. As herein shown, the plate B is provided within the walls I) If witha series of prominences or studs, 1), upon which the bed 0 rests.

D is a supply-pipe for the liquid fuel, said pipe being connected with the bottom plate, B, of the box B, and arranged to open within the trough B", so as to supply oil to the bot- 7o torn of the porous bed therein. In the particular construction illustrated the supplypipe D is connected with a depending boss, I)", cast upon the lower surface of the said plate B, and said boss is extended somewhat below the point at which the supplypipe is connected therewith, and is provided with a short vertical pipe, B,containing a valve,b whereby residuum or sediment from the oil or fuel accumulating in the bottom of the trough B may be discharged therefrom.

E E are two walls or plates extending at either side of and above the box B, and connected at their ends with other vertical walls or plates, E, in such manner as to form a casing to the burner, inclosing an open space or combustionchamber, F, above the top of the porous bed 0. The lower parts of said walls E E are arranged to extend outside of the box B, and are placed at such distance apart as to 0 leave a space or opening for the influx of air to the combustion-chamber, and the upper parts of said walls are converged or brought together, so as to deflect the air entering at the bottom of the casing inwardly over the top of 5 the porous bed. In the particular construction of the parts herein shown the lower part of one of the walls E is placed in contact with one side of the box B and the end walls, E, in contact with the ends of the said box, the other of the said walls Ein this instance the one remote from the front of the stove-being arranged at some distance from the inner side wall, I), of the said box, so as to form a vertical passage, f, between the box and the said wall E, leading into the combustion-chamber F above the porous bed. At their upper margins the walls E E E E are attached to a flat top plate, G, which is supported upon the walls of the stove, and is provided with an opening, 9, through which the products of combustion may pass from the top of the chamber F, said opening 9 being controlled by a sliding valve, H, as will be hereinafter more fully set forth. For attaching the plates E E E E to the horizontal top plate, the said plate G is provided with depending lugsgg, to which the upper parts of the plates E E E E are bolted. Thebox B is attached to the plates E E by means of lugs b b, through which lugs and corresponding projections upon the plates E E are inserted bolts for holding the parts together.

In the operation of the burner the oil admitted to the trough B rises through the porous bed, and is burned at the top of the latter. The oil is fed continuously to the trough in quantity (usually determined by a regulating-valve) to give a flame of a desired size or intensity. In case oil flows to the trough B at any time more rapidly than it is consumed, the surplus will overflow into the spaces or receptacles formed within the box B by the partition-walls b b, and will there remain until vaporized by the heat of the box or trough. Such overflow will commonly occur only when the burner is first lighted and the parts are cold, combustion taking place more slowly at such time than after the porous bed and adja cent parts have been highly heated.

The unitary structure, comprising the box B, the walls of the chamber F, and the horizontal plate G, said parts forming the principal parts of the burner, is obviously sustained or supported entirely by said horizontal plate, which latter may be attached within the walls of a stove or range and adapted either for heating or cooking without other change than that required for fitting the said plate G to the ad jacent parts of the stove or range. When a burner comprising the parts above mentioned is employed in a stove or other heating device especially constructed to receive it, said plate will of course form part of the structure.

In a burner intended for application to stoves or heating apparatus already built I preferably employ a novel feature of construction in the plate G, whereby the latter may be easily changed in size to correspond with the parts to which it is to be attached, and consisting of a series of grooves or channels, g 9 formed in the marginal part of the plate and 4 adapted to allow strips of metal to be broken off and removed from the edgesof the plate, so as to make the latter of a desired size. In

vice for heating water.

the particular construction of the parts herein illustratedthe plate G is constructed to rest at its rear part upon the horizontal plate A of the stove, and a support for the edge of the said plate G at the front of the stove is provided by means of brackets a a, bolted to the frontwall, A, as clearly shown in Fig.1. The

' instance the plate G is rectangular, and grooves fig are provided opposite to each other in both sides of the plate, said grooves being parallel with the sides and ends of the'plate and arranged at short distances apart to allow relatively narrow strips to be broken from the plate. It will of course be understood that strips of a greater or less width will be broken from the edges of the plate, and more at one side than another, as found necessary to make the plate fit the stove and to bring the parts supported by the plate in proper position therein.

The valve or damper H, herein illustrated, consists of a'thick metal plate resting upon the top surface of the plate G, and held or guided in its horizontal movement by guide-flanges g 9 upon the said plate G, at either side of the opening g. Any convenient construction in actuating device for the damper H may be employed-such, for example, as that shown in the said prior application, No. 210,046. I have herein shown a device for this purpose consisting of a horizontal rotating shaft, I, located below and parallel with the said valves H, and provided with a pinion, i, engaging a rack, h, formed on the under surface of said valve. The said shaft I extends at one side of the stove through the outer wall, A, thereof, and is provided with a hand-wheel, 1, whereby the shaft may be readily rotated and the valve moved.

J is a sliding valve or damper arranged to control the lower opening of the passagef by which the air is admitted to the top of the porous bed O. Said valve is held at its ends in guide-groovesjj, formed at the lower margins of the end-plates, E E, and is provided with a handle, j, whereby it may be moved, said plate being constructed to slide backwardly beneath the box B when opened. A simple means of forming the guidegroovesjj is herein shown, consisting of angle-irons J J bolted to the lugs b b, and below and parallel with flangesj j upon the lower edge of the end plates, E E.

In Fig. 3 I have shown a burner'whieh is generally similar to that shown in Fig. 1, and which is constructed with especial reference to use in a stove having a water-back or de- In said Fig. 3,K represents a water-back, herein shown as'consisting ofa metal block or casting containing a tortuous water-passage, 70, said water-back being located against the outer front wall, A, of the stove. In this instance the wall E of the IIC combustion 4 chamber adjacent to the waterback is made flat and vertical, or approximately s'o,to fit the inner face of the said water-back, and is cut away or apertured, as indicated at f, so as to allow direct access of the flame to the surface of the said waterback.

Fig. 4 illustrates aslight modification of the construction shown in Fig. 3, intended for use in case the water-back is placed in an inclined position in the stove, as is sometimes the case. As shown in said Fig. 4,the wallE of the combustion-chamber adjacent to the water-back is connected with the box B by means of horizontal pivotsf f so arranged as to allow the said wall E to be placed in an inclined position corresponding with the inclination of the adjacent surface of the watei back K. In order to close the opening at the ends of the combustionchamber, which would be caused by the movement of the side wall, E, in the manner described, said wall E is constructed at its ends with flangesf extending toward and overlapping the adjacent parts of the end walls, E, as clearly shown in the said drawings, Fig. 4.

In the said prior application, No. 210,046, the burner therein illustrated is shown as consisting of four different parts or castings arranged to provide an exterior casing for the burner and trough for the oil, a shell or casing without bottom or top, into the lower part of which the porous bed is placed, and a top plate provided with a flange depending within the said casing or shell to a point near thetop of the porous bed, the said exterior casing being provided with a tight bottom extending beneath the oil-holding trough to receive and hold surplus oil which may overflow from the said trough.

In the construction herein illustrated both the oil-trough and overflow receptacle or receptacles are formedin a single box by means of walls or partitions therein, and said box is attached to the lower margins of the casing, forming the combustion-chamber, thus affording a much more cheap and simple construction in the parts than that shown in said prior application.

I claim as my invention 1. A burner for liquid fuel,co nprising a box or trough provided with a wall or walls, I), forming an oil-holding receptacle, and an overflow receptacle or receptacles,means forsupplying oilto the trough, and a casing attached to and sustaining said box or trough, said casing being provided with an air-inlet'opening for the access of air to the burner, substan tially as described.

2. A burner for liquid fuel,eomprising abox or trough provided with a wall or walls, I), forming an oil-holding receptacle 0r receptacles, and an overflow receptacle or receptacles, means forsupplying oil to the trough, a casing consisting of side and end walls, attached to said trough and forming a combustion-chamber above the receptacle, and a horizontal plate or casting attached to the casing and provided with an opening for products of combustion, substantially as described.

3. The combination, with a stove provided with a water-back, of an oil-burner comprising a porous bed, means for supplying oil to the said bed, and a combustion-chamber located above the bed, the wall of said chamber adja cent to the waterback being apertured or cut away to allow access of the flame to the said water-back, substantially as described.

t. The combination, with a stove provided with an inclined water-back, of aburner comprising a porous bed, means forsupplying oil to said-bed, and a combustion-chamber, one of the side walls of which is made movable to allow it to be placed in contact with the inclined surface of the water back, substantially as described.

In testimony that I claim the foregoing as my invention I atfix my signature in presence of two witnesses.
